The upper than the width of the envelope which the mavthe shaft 21.

chine is designed to contain. The length of the plate is also somewhat greater than that of the envelope to be sold, as indicated in Fig. 2.

17 indicates a plate, which is mounted upon the under side of the plate 10, and is adapted to move longitudinally of said plate. rPhe plate 17 is held in position by guides 18, as best shown in Fig. 5.

19 indicates a pin carried by the plate 17, which pin projects upward through the slot 13 in the plate 10, and terminates a short distance above said plate.

20 indicates a rack, which is formed on the under side of the plate 17, and extends longitudinally thereof. I prefer to form the rack 2O and plate 17 integral with each other, but they may be separate if desired.

2l indicates a shaft, which is mounted in suitable bearings formed in hangers 22 and 23. The hangers 22 and 23 are shown as depending from the plate 10, but any other suitable construction may be used for supporting The shaft 21 extends transversely of the machine, as shown in Figs. 3 and 4, and-extends to the outside of the machine, as best shown in Fig. 3.

24 indicates a handle or crank, which is mounted upon the outer end of the shaft 21, as best shown in Figs. 3 and 4.

25 indicates a gear, preferably a mutilated gear, which is mounted upon the shaft 21 immediately under the rack 20, with which its teeth intermesh. The arrangement is such that by rotating the shaft 21 in the direction indicated by the arrow in Fig. 2, the gear 25 will cause the rack 2O and plate 17 to move in the direction indicated by the arrow in Fig. 2, thereby moving the pin 19 in the slot 13 away from the center of the plate 10. A reverse rotation of the shaft 21 will cause the pin to move in the opposite direction.

26 indicates a spring, preferably a coiled spring, which is adapted to cause the shaft 21 to rotate in the direction opposite to that indicated by the arrow in Fig. 2, thereby acting to hold the parts in the position shown in Fig. 2. One end of the spring 26 is secured to the plate 10, while the other end is secured to the shaft in such manner that by the rotation of the shaft in the direction indicated by the arrow in Fig. 2, the spring will be `coiled up.

28 indicates a cylinder, which is secured to the under side of the plate 10, in a position parallel to the slot 13. The end of the cylinder 28 which lies nearer the center of the plate 10, is open, as shown in Fig. 3.'

29 indicates a piston rod, which carries a piston head 30 adapted to move in the cylinder 28, as shown in Fig. 5. The outer end of thegrpd 29 is attached tothe plate 17, as shown in 5. By-thisconstruction, when the plate 17 is moved in the direction indicated by the arrow in Fig.'5,lthe piston head 30 will `move toward the open end of the cylinder 28. When the plate 17 returns from its former position under the action of the spring 26, as above described, the piston 30 will compress the air in the cylinder and serve as a check to prevent the too rapid return of the plate 17.

31 indicates a bevel gear, which is loosely mounted upon the shaft 21 at one side of the plate 10, as shown in Figs. 3 and 5. The object of the gear 31 will be more fully hereinafter set forth.

32 indicates a Wheel, which is preferably mounted upon the gear 3l and is concentric therewith. Instead of mounting the Wheel 32 upon the gear 31, it may be mounted upon the shaft 21, if desired, and connected to the gear 31. The wheel 32 is provided at diametrically opposite points on iis periphery, with slots or depressions 33 and 34, as shown in Fig. 6.

35 and 36 indicate lugs, which project from the side of the periphery of the wheel 32, at points ninety degrees from the depressions and 34, as also shown in Fig. 6. The lugs 35 and 36 project abruptly from the wheel 32 on one side, and on the other side they slant gradually to the surface of the wheel.

37 indicates a dog, which is pivotally mounted upon the shaft 21 at a point near the wheel 32, as best shown in Fig. 5. The dog` 37 is mounted upon a pin 38, which passes through the dog and the shaft 21; the dog being pivotally mounted in such manner that it may be rocked in a plane parallel to the axis of the shaft 2l.

39 indicates a screw, or adjustable pin, which passes through a lug 40 carried by the dog 37, and is adapted to engage the shaft 21. Byadjusting the position of the screw 39, the distance which the dog 37 may be rocked may be regulated as desired.

41 indicates a pin, which is carried by the shaft 21 on the side opposite to that on which is placed the screw-39, and projects upward therefrom through a recess in a lug 42 projecting from the dog 37, which pin is also adapted to engage the shaft 21.

43 indicates a spring, which is mounted upon the pin 41 between the lug 42 and the shaft 21. The tension of the spring 43 tends to move the dog 37 toward the wheel 32.

44 indicates a shoulder which is formed on the side of the dog 37 at right angles to the wheel 32. The shoulder 44 is adapted to engage the lugs 35 and 36 on the wheel 32 when the dog 37 is moved toward the wheel 32, as will be hereinafter more fully set forth.

45 indicates a tooth, which is carried by the dog 37 and projects at right angles therefrom toward the wheel 32; the object of which tooth will be more fully hereinafter set forth.

46 indicates a coin chute, the upper end of which coincides with a second chute 47 formed in the cover 2 of the casing. A slot is formed in the cover to permit of access to the chute 47. The lower end of the chute 46 terminates near the periphery of the wheel 31, as shown in Fig. 1, and is provided with a curved slot 48. The slot 48 is formed on the arc of a cir- IOO IUS

cle of which the radius is equal to the distance of the tooth 45 of the dog 37 from the center of the shaft 21, and the arc of the circle upon which the slot 48 is struck is concentric with the wheels 31 and 32. The plate which forms the inner wall of the chute 46 is inclined at the upper end of the slot 48, as shown in Figs. 6 and 8, the object of which will be hereinafter set forth.

49 indicates a dog, which is pivotally mounted in the lower end of the chute 46,as shown in Fig. 7. The inner end of the dog 49 projects into the chute a short distance, audits outer end projects over the periphery of the wheel 32.

50 indicates a tooth formed on the outer end of the dog 49, which tooth is adapted to enter the recesses or slots 33 and 34.

51 indicates a spring, which is located between the outer end of the dog 49 and the adjacent portion of the plates which form the chute 46; the tension of which spring acts to hold the tooth 50 of the dog 49 in contact with the periphery of the wheel 32. When the tooth 50 is in any one of the recesses or slots of the wheel 32, the wheels 31 and 32 will be locked in position. The tension of the spring 51 is sufficient to prevent the weight of a coin upon the inner end of the'dog49 from throwing the tooth 50 out ofthe slots 33-34. When a coin, as 52, is dropped in the chute 47, it will pass downward to the lower end of the chute 46, where it will rest upon the inner end of the dog 49, as shown in Fig. 7. The various parts will at this time be in the position shown in Figs. 5 and 6. By slightly rotating the shaft 2l in the direction indicated by the arrow in Fig. 6, the dog 37 will be moved in a similar direction, and the tension of the spring 43 will move the outer end of the dog 37 toward the wheels 31 and 32, the incline at the upper end of the slot 48 permitting of such inward motion. The tooth 45 will then pass into the slot 43 above the coin 52, as the dog 49 is so located as to arrest the coin at a point slightly below the upper end of the slot 48. By continuing the rotation of the shaft 21, the tooth 45 will engage the upper edge of the coin 52, and will press it downward,causinga downward pressure to be brought upon the inner end of the dog 49, and thereby overcoming the tension of the spring 51 and withdrawing the tooth 50 from the slot 34. This will leave the wheel 32, and consequently the wheel 31, free to rotate. By rotating the shaft 21 still farther, the shoulder 44 will come in contact with the lug 35 on the wheel 32, and` will -rotate the wheels 31 and 32. The rotation of the shaft may then be continued until the slot 33 arrives opposite the tooth 50, when said tooth will enter the slot and prevent further rotation of the wheel, and consequently of the shaft 21. As the slots 33 and 34 are placed diametricall y opposite each other, only i tilted, as above described, the coin will pass down through the lower end of the chute and into the receiver. The tension of the spring 26 will return the parts to the position shown in Figs. 5 and 6, as soon as the half rotation is completed, as above d escribed. At the time the above operation takes place, the rotation of the shaft 21 will have caused the gear 25 to move the rack 20, as hereinbefore described, and the pin 19 will be moved in the slot 13 away from the center of the plate 10.

In order to prevent the return of the shaft 21 and the various parts to their normal position beforea full half rotation of the shaft is completed, a lever 53 is provided, which is mounted upon the shaft 21 immediately outside of the gear wheel. 31, as best shown in Fig. 5. A

54 indicatesa pawl which is pivotally mounted upon the outer end of the lever 53, and is normally held in a position parallel thereto by a spring 55, which is connected at one end to the rear end of the vpawl 54, and at the other end to the base of the lever 53. The outer end of the pawl 54 is squared, as shown in dotted lines in Fig. 1, and is adapted to engage the teeth of a curved rack 56, which extends through an arc of a little\more than ninety degrees, and is suitably secured near the periphery of the Wheel 32, and at a point distant from the shaft 21 slightly less than the combined length of the lever53 and pawl 54. The arrangement y is such that as the shaft 21 is rotated in the direction indicated by the arrow inFig. 1, as the pawl comes in contact with the teeth of the rack 56, it will be turned backward, as shown by dotted lines IOO in Fig. 1, and will thereby serve as a lock to prevent the reverse movement ofthe shaft 21. As soon as the shaft 21 has been rotated sufficiently to carry the pawl 54 beyond the upper end of the rack 5 6, the motion of the shaft may be reversed, as thev pawl will be turned in the opposite direction..

57 indicates a beveled cogged ring, the diameter of which is slightly less than that of the interior of the casingl. The ring 57 is adapted to rest upon the four corners of the plate 10, and it is held in place by means of lugs 58, which project upward, as shown in Figs. l and 9. The gear 31 is so placed as to intermesh with the cogs of the ring 57, as best shown in Fig. 3. By this construction, when the gear 3l is rotated, the ring 57 will be rotated in a horizontal plane. The relation of the gear 31 and ring 57 to each other is such that by giving the gear 31 half a revolution,

the ring 57 will be given-a quarter of a revolution; the object of vWhich'arrangement will be more full'y hereinafter set forth.

59- 60- 61- 62 indicate uprights, rectangular in shape, which rise from the ring 57 at points ninety degrees from each other. These uprights are preferably-secured upon the ring 57 by screws, but they may be secured thereto in any other suitable manner.

lThe angles of the uprights are placed nearest the center of theplate/lO, and one edgeof each of the uprights is placed parallel to the shoulders 16, as shown in Fig. 4. The uprights are designed to hold the envelopes and to feed them to the apparatus which carries them out of the machine. In placing the envelopes in position they are arrangedl criss-cross; that is, being placed alternately at right angles to each other in two piles, as shown in Figs. 2 and 3 and as indicated by dotted lines in Fig. 4. When the lowermost envelope lies parallel with the shoulders 16, it will rest upon the bottom of the plate 10, and one end will be opposite the slot 15. The pin 19 will at this time be at the outer end of the slot 13. The envelope next to the bottom will be at right angles to the lowermost one, and will rest upon the shoulders 16, as indicated by dotted lines in Fig. 4 and shown in Fig. 2.

To deliver an envelope, a coin of suitable size is dropped into the chutes 47 and 46, and will finally come to rest upon the inner end of the dog 49, as shown in Fig. 7. By rotating the shaft 21 in the direction indicated by the arrow in Fig. 1, by means of the crank 24, the dog 37 will move in the direction indicated by the arrow in Fig.l6, and the tooth 45 will enter the slot 4S at a point above the coin, as indicated in Fig. 6. By continuing t-he rotation of the shaft 21, the tooth 45 will press the coin downward out of the slot, thereby raising the outer end of the dog 49 and releasing the wheel 32. The shoulder 44 will then engage a lug 35 and will give the wheels 31 and 32 halt' a complete rotation. As soon as the slot 33 arrives opposite the tooth 50 of the dog 49, said tooth will enter the slot and prevent further rotation of the gear 31 and wheel 32. By rotating the gear 3l as above described, the ring 57 will be given a quarter of a revolution, thereby moving the uprights an equal distance and moving the next envelope parallel to the shoulders 16 and permitting it to rest upon the plate l0. When the shaft21 is rotated', as above described, the pin 19 will be moved away from the center in the slot 13, as has been hereinbefore described, until it reaches the outer edge of the plate 10 and passes beyond the edge of the lowermost envelope. The envelope will then be dropped between the pin 19 and the slot 15. When the shaft 21 returns to its former position, by the action of the spring 26, the pin 19 will bear against the envelope and will move it along the plate l0, as indicated by the arrow in Fig. 2, thereby moving the end of ita short distance through the slot 15, as indicated by dotted lines in Fig. 2. The envelope may then be easily grasped by the purchaser and removed.

63 indicates a hub, which is mounted upon the inner end of the shaft 2l, as shown in Fig. 5. The hub 63 is provided with an eccentric flange 64 on its face, the outer portion of which gradually narrows until it becomes even with the face of the hub, as shown in Fig. 5.

65 indicates a spring bell striker, or hammer, which is adapted to engage the iiange 64 when the shaft 21 rotates. The arrangement is such that as the shaft 21 rotates, the striker will move upon the flange until it reaches the narrow portion of the fiange, when it will be thrown off, and will return suddenly to its former level under the spring of the striker.

66 indicates a bell, which is mounted in suitable position to be struck by the striker 65 when it slips off the fiange 64. By this arrangement, at each semi-rotation of the shaft 21 in the direction indicated by the arrow in Fig 9, the bell will be struck.

I have shown a single slot 13 in the plate 10 and a single pin 19, but it is evident that any desired number of slots and pins may be provided.
